Thanks folks!
Evan: That Ilmavoimat D.520F was, of course, inspired by a combination of French Hawk 75As rebuilt for Finland and the local Klimov-powered Mörkö rebuilds.
EH: The LVF was a real formation (eventually becoming 33 SS Charlemagne) but I made up the aviation component. (Originally, I was thinking of Vichy going over to the Axis after Oran but the schemes looked too Italian.)
Elsewhere, Greg was asking about further developments of the Dewoitine D.520. I've got a few of those in the works ...
